Participate in a Study on Depression

We are looking for participants with depression to take part in a study on the impacts of early-life stress on the immune system, the gut microbiome (bacteria living in the gastrointestinal tract), and severity of symptoms.

If you are:
- Between 25 and 55 years old
- Diagnosed with depression or having difficulty with depressive symptoms
- Not suffering from medical (e.g., inflammatory, cardiovascular, liver diseases) or other psychiatric (e.g., bipolar disorder, obsessive compulsive disorder, psychosis) conditions
- Wondering if gut bacteria could affect mood

You may be eligible to participate in a study looking at whether changes within the immune system and the gut microbiome are more pronounced in depressed individuals with a history of childhood adversity and are aligned with the severity of depressive and anxiety symptoms.

Participation in this study will involve:
- A first session of approximately 2.5h during which you will:
o Complete a structured interview with a clinical psychologist to determine your eligibility
- If you are eligible, a second session of approximately 1h during which you will :
o Provide a blood sample
o Complete 3 study questionnaires
- Provide a stool sample (collected at home and returned in person to our lab)

In appreciation of your time you will receive a monetary remuneration.
